The Colorado Real Estate Commission’s Seller’s Property Disclosure form has fields most Denver sellers fill in wrong. Here is what the form actually requires, why Denver’s housing stock makes the stakes especially high, and what post-closing liability looks like when a buyer finds something you left off.
Summer is when Denver sellers make the disclosure calculation. The house goes on the market, the listing agreement gets signed, and somewhere in the paperwork stack lands the Seller’s Property Disclosure form — a document most sellers treat as a formality and their attorneys, later, treat as evidence.
Denver’s particular housing inventory makes that calculation harder than in most markets. Capitol Hill and Park Hill are full of 1920s bungalows with knob-and-tube wiring, galvanized plumbing, and unfaced pipe insulation. Cheesman Park and Curtis Park have condo conversions in older buildings where the HOA is managing litigation no one mentions at showings. And essentially every neighborhood from Stapleton west to Lakewood sits in one of the top hail-exposure corridors in the country, generating insurance claims, contractor repairs, and permit questions that follow a house for years.
This piece walks through the Colorado Real Estate Commission’s current Seller’s Property Disclosure form — focused specifically on what Denver sellers most often underreport, why, and what happens after closing when a buyer figures it out.
What the Colorado SPD Form Is and Who Has to Use It
The Seller’s Property Disclosure is a standardized document issued by the Colorado Real Estate Commission, available at dre.colorado.gov. Any seller working with a licensed Colorado real estate broker must complete it. This is not a statutory requirement under Colorado law — it’s a CREC rule, which means it applies whenever a licensed broker is involved on the seller’s side, regardless of whether the buyer has representation.
FSBO sellers aren’t technically required to use the SPD form. But they’re not off the hook. Colorado is not a caveat emptor state. Sellers have a common law and statutory obligation to disclose material known defects regardless of whether they complete a formal disclosure form. The SPD is simply the most defensible way to document that obligation has been met.
One point that trips up a lot of Denver sellers every year: listing a home “as-is” does not eliminate the disclosure requirement. An as-is sale signals the seller won’t negotiate credits or repairs. It does not create a legal shield against the obligation to disclose known defects. A buyer who discovers an undisclosed material defect after closing can pursue the seller in Denver County District Court regardless of what the contract said. I’ve heard sellers confidently explain otherwise to their agents. They were wrong.
The SPD form organizes disclosure obligations into sections covering structure, roof, electrical, plumbing, HVAC, environmental conditions, water and sewer, HOA status, and legal matters. Sellers sign it under oath. That detail matters considerably when disputes end up in court.
Hail Damage and Insurance Claims — The Disclosure Question Most Denver Sellers Get Wrong
Denver and the surrounding metro rank among the most active hail markets in the country. If you’ve owned a home along the Front Range for more than three or four years, you’ve almost certainly weathered at least one significant storm. Many sellers have filed claims — sometimes more than one.
The disclosure error that recurs most often: a seller files a claim, receives a payout, hires a contractor, gets a new roof, and decides the matter is closed. It isn’t. The SPD form asks about prior insurance claims related to the property — not just current damage. A paid and resolved hail claim still must be disclosed. Buyers and their lenders use this history to assess insurability going forward. In a market where some insurers are now declining to write new policies on properties with multiple prior claims, that history is material. Buyers need to know.
The roof section of the form then requires separate disclosure about the current roof’s age, condition, type, and any known defects. A seller who had a full replacement done by a storm-chaser contractor — extremely common after large metro Denver hail events — faces a compounding problem if that work was done without pulling a permit from Denver Community Planning and Development (CPD). Unpermitted roofing creates simultaneous disclosure obligations in the roof section and the permits section. Sellers who disclose the insurance claim but stay silent about the unpermitted work have only partially completed their obligation.
The permit issue isn’t minor. Denver CPD requires a roofing permit for most roof replacements. When contractors skip it — as storm chasers who work quickly and at volume sometimes do — the work isn’t inspected and there’s no city record that it meets code. A buyer who discovers this after closing faces potential remediation costs and a potential problem with their own insurer.
Radon Tests Don’t Age Out
Colorado’s Front Range geology — granitic soils with elevated uranium content — produces elevated radon levels statewide. Colorado ranks among the top 10 states for radon risk, and the Denver metro sits squarely in the high-risk zone. The state’s average indoor radon level runs around 4 pCi/L, notably higher than the national average of roughly 1.3 pCi/L.
Denver sellers frequently ask whether a test result from five years ago still needs to be disclosed. Yes. Colorado’s disclosure obligation is keyed to what the seller knows, not when they learned it or whether the information is current. A 3.8 pCi/L result — just below the EPA and CDPHE action level of 4 pCi/L — is borderline information that a reasonable buyer would want. The test being old doesn’t transform it into unknown information; you know what it said. Checking “no known issues” on the environmental section when you have a documented borderline test result is a misrepresentation.
Sellers who installed radon mitigation systems face an additional wrinkle. The SPD form asks whether a mitigation system exists. If you installed one, you must disclose it. And if that system hasn’t been tested or serviced since installation — common in homes where the seller put it in to satisfy a prior buyer years ago and then forgot about it — you have an obligation to know its current status before you sign the form. A mitigation system in disrepair described as “present and operational” is also a misrepresentation.
CDPHE recommends retesting every two years in high-risk areas. If your last radon test is more than two years old, schedule a new one before you list. A current result from a functioning mitigation system is a considerably stronger disclosure position than an aging borderline number with no follow-up.
HOA Litigation and Conflicting Disclosure Obligations
Sellers in Denver’s older condo stock — Capitol Hill conversions, LoDo loft buildings, buildings along Colfax and in the Uptown corridor — face a disclosure issue more complicated than what applies to single-family homes.
The SPD form’s legal matters section asks whether the property, or in the case of a condo, the HOA, is involved in any pending or threatened litigation. If yes, it belongs on the form. This obligation rests with the seller and is independent of anything the HOA provides.
Colorado’s Common Interest Ownership Act (CCIOA), codified at C.R.S. § 38-33.3-209.4, imposes a separate obligation on the HOA itself to provide a Status Letter to any unit owner who requests one. The Status Letter covers litigation, assessments, and the association’s financial condition. In a condo sale, buyers are entitled to a CCIOA Status Letter, and sellers are responsible for requesting it and providing it. Many sellers assume that because the HOA Status Letter addresses litigation, they don’t also need to disclose it on the SPD form. That assumption is wrong. Neither document substitutes for the other. For a broader look at HOA homeowner rights under Colorado law, including what CCIOA requires of associations in disputes, that framework matters to sellers and buyers alike.
The additional complexity in Denver’s older buildings comes down to what you’ve actually read. If you’ve received HOA meeting minutes — whether you requested them or they arrived in an email you probably skimmed — and those minutes reference a pending lawsuit, a threatened construction defect claim, or a special assessment tied to litigation, you possess that knowledge. You cannot sign the legal section “not applicable” when you have meeting minutes in your inbox that say otherwise. Colorado courts have applied a “knew or should have known” standard that includes information a seller received and reasonably should have read.
Construction defect litigation is a particular exposure point for buildings developed or converted between the 1980s and mid-2000s, before the Colorado Construction Defect Action Reform Act (CDARA) made such suits harder to bring. If you own in one of those buildings and you haven’t read your HOA minutes carefully in a while, now is the time.
Unpermitted Work and Denver’s Searchable Public Records
Denver CPD’s building permit records are publicly searchable at denvergov.org. Buyers’ agents, inspectors, and appraisers check them routinely. This is standard practice in Denver residential transactions and it takes about two minutes. Sellers who leave unpermitted work off the form and hope no one notices are operating on a false assumption.
The most common unpermitted work in Denver residential sales follows a recognizable pattern. Finished basement bedrooms without a permit are probably the single most frequent issue, and they intersect with an additional problem: a basement room without a code-compliant egress window cannot legally be called a bedroom. It’s a “bonus room” or “flex space” in the listing. Market it as a bedroom and you’ve created a misrepresentation in the listing itself — separate from and in addition to the disclosure form problem.
Deck additions are the second most common. Decks over 30 inches above grade require permits in Denver, and work done without one may not meet code for ledger attachment, footing depth, or railing height. Garage-to-ADU conversions have become increasingly common since Denver expanded ADU allowances through rule updates adopted in 2021. Converting a garage to a living unit requires multiple permits — building, electrical, and mechanical at minimum — and many older informal conversions have none.
The SPD form’s permits section asks directly whether any improvements were made without required permits. The disclosure obligation is clear. The practical reality: unpermitted work discovered during a buyer’s inspection typically results in a demand for either a credit covering remediation costs or a requirement that the seller pull a retroactive permit and bring the work to current code before closing. Either path is expensive and disruptive. Disclosing upfront, pulling a permit before listing where possible, or pricing the property to reflect the work’s status are all more defensible than silence. None of them are fun. But they beat what comes after.
Pre-1980 Denver Homes and What Inspectors Will Find
If your home was built before 1980, a reasonably thorough buyer’s inspector will flag several categories of potential concerns that belong on the SPD form. Sellers in Capitol Hill, Whittier, Park Hill, Washington Park, and the Highlands should expect to address most of these. There’s no getting around the age of the housing stock.
Asbestos-containing materials were standard in residential construction through the late 1970s. In Denver homes of that era, the most common locations are pipe insulation in mechanical rooms and basements, floor tiles (9x9-inch vinyl tiles are a strong indicator), and popcorn ceiling texture. The SPD form asks about known asbestos-containing materials. The critical distinction: sellers who haven’t tested cannot check “no.” If you don’t know, the answer is “unknown.” Checking “no” when you’ve never had the home tested is a misrepresentation.
Knob-and-tube wiring appears in nearly every Capitol Hill bungalow built before roughly 1940. It’s not automatically unsafe, but it’s ungrounded, it can’t support modern electrical loads, and many homeowners’ insurers won’t write policies for homes where it’s active and unenclosed. If you know it’s present, it belongs on the electrical section of the form.
Homes built before roughly 1960 frequently have galvanized steel supply lines. Galvanized pipe corrodes from the inside out, reducing water pressure over time and eventually failing. If you’ve noticed reduced water pressure and never investigated, you own that information.
Denver’s expansive clay soils swell with moisture and shrink in dry conditions. Older brick and unreinforced concrete foundations in Capitol Hill and Park Hill move with those soils over decades. Sellers who’ve noticed stair-step cracking in exterior brick, diagonal cracking above door frames, or doors that started sticking — all common indicators of differential settlement — have material information to disclose. Chalking it up to “old house” is understandable. It doesn’t change the disclosure obligation.
Homes predating the 1970s typically have clay-tile sewer laterals running from the house to the main. These are fragile, deteriorate over time, and are particularly prone to root intrusion. Sellers with known sewer issues have a material defect to disclose. Sellers who’ve never scoped the lateral may legitimately characterize their knowledge accordingly — but in Denver’s older neighborhoods, a pre-listing sewer scope has become standard seller preparation precisely because buyers and their inspectors almost always request one anyway. Do it before you list.
Federal law also requires separate disclosure under HUD/EPA rules. Sellers of homes built before 1978 must provide buyers with a Lead-Based Paint Disclosure addendum, any known records of lead-based paint or hazards, and the EPA’s “Protect Your Family” pamphlet. This is a distinct obligation from the SPD form, and sellers who skip it face potential HUD enforcement independent of Colorado state law.
What Post-Closing Liability Actually Looks Like in Denver
The part of the disclosure conversation that gets the least specific coverage is what actually happens when a buyer discovers an omission after they’ve moved in and closed escrow. It’s also the part sellers are most tempted to avoid thinking about.
Colorado’s legal framework for non-disclosure claims runs on two tracks: fraudulent concealment (the seller knew of a defect and intentionally hid it) and negligent misrepresentation (the seller made a false statement without exercising reasonable care to verify it). The operative standard in most Denver disputes is “knew or should have known” — a broad one that covers what sellers actually knew and what they had reasonable opportunity to learn. A seller who checked “no known issues” in the structural section while living for three years with sticking doors and stair-step cracking faces a difficult argument that they had no reason to suspect a foundation problem.
“I forgot” and “I didn’t think it was important” are weak defenses on a form signed under oath. Courts have been consistent on this. The materiality question — whether a reasonable buyer would have considered the information important to the decision to purchase, or to the price they were willing to pay — is generally not close when the undisclosed item is a foundation problem, a basement bedroom with no egress window the buyer believed was legal, or a construction defect suit about to levy a special assessment on every unit in the building.
Denver County District Court has awarded remedies including rescission of the sale, repair-cost damages, and diminution-in-value claims where rescission was impractical. The piece most sellers don’t know: buyers have three years from the date of discovery to act — not three years from closing. A buyer who discovers an unpermitted basement conversion when they try to refinance two years after closing, and who can show the seller knew, has three years from that discovery date to file. For defects that don’t manifest immediately — slow foundation movement, a latent drainage problem — the discovery date can be years after the closing date.

Before You Sign the Form — A Pre-Listing Checklist for Denver Sellers
The SPD form is due at or before contract. That means the time to address its contents is during listing preparation — not when you’re under contract and on a tight inspection-period clock, which is exactly how sellers end up making hasty decisions they regret.
Pull your permit history first. Denver CPD’s permit portal at denvergov.org lets any user search by address. Pull every permit on record and compare it against the work you know has been done. Gaps are disclosure items, and some are worth resolving before you list.
Gather any inspection reports from your own purchase or from prior sales attempts and actually read them. Any defect flagged in a prior report that you haven’t repaired is material known information. Sellers who’ve had inspection reports sitting in a drawer for three years have difficulty arguing they had no knowledge of what those reports documented. For a detailed look at what Denver home inspectors flag most often in local housing stock — and why the findings matter in negotiations — that resource covers the buyer-side view of the same properties sellers are disclosing.
For HOA properties, request the CCIOA Status Letter and the last 12 months of meeting minutes before you list. Status Letters take time, and you don’t want to be scrambling for them mid-transaction. Read the minutes. If litigation, pending litigation, or a threatened claim appears anywhere in those minutes, it belongs on your disclosure form.
Schedule a current radon test if your last one is more than two years old, or if you’ve never tested. A current result from a properly functioning mitigation system is the strongest possible disclosure position.
Pull your claims history from your insurer if you don’t have records. Every paid claim within your ownership period is potentially disclosable, and hail claims need to be paired with documentation of how and whether the work was permitted.
In a pre-1970 Denver home, if you haven’t had a sewer scope done in the last several years and have no records of one, schedule it. Knowing what’s in the lateral before you describe your knowledge on the form is a stronger position than finding out during the inspection period. It usually costs $150 to $250 — not much against what a mid-transaction discovery costs everyone.
Proactive disclosure is uncomfortable. Putting known defects on paper feels like voluntarily giving away negotiating leverage, and I understand that instinct. But the alternative is specific: signing a form under oath that omits material information you possess creates a post-closing exposure that can follow you for years. The buyer who paid $750,000 for your Park Hill bungalow and discovered six months later that the basement bedroom has no egress window and the roof replacement was never permitted is not going to let either one go quietly.
Denver’s market has spent years rewarding sellers. That doesn’t touch the disclosure obligation, which is identical whether your house gets ten offers in a weekend or sits on the market for six weeks. The legal standard for what a seller knew and should have disclosed doesn’t move with inventory levels or interest rates. Worth remembering when the temptation to leave something off feels strongest.
